In the last two weeks there have been 4 Hi-jackings between the Paper Millls and Rand Water Board pump station MTB trial. These have all been executed by two very dark in complextion 25-30 year old males who move out of the path to let you pass and then grab your arm with a resulting crash. Armed with a panga and knife each they attack you while still dazed and flee with your bike. Yesterday's loss, a Giant Anthem 1 and Specialized Epic! Ride in groups of 4 plus!
